1 cam. (01. 53-3) invention relates to a combination unit, in which drip coffee can be made, with a detachably connected insulated receiver for retaining the hot coflee for later service.

it There has long been a need for a device which will retain coffee previously made in a fresh, hot condition. heating, boiling, or reheating, provides a coflfee with a bitter taste; such stale cofiee often rem sulting in giving one a headache. It is among the objects of my inventionto provide a device in which fresh drip coffee may be made and retained in an insulated portion of my device for later service. No laborious and annoying transit ier toextraneous apparatus is necessary. All the original aroma and rich, beneficial, stimulating oils are conserved, and the coffee later served is uniformly hot, sediment free, full flavored and delicious. My device is rapid in operation, algo ways available, economical in original cost and upkeep. Fuel is saved, and there is no stale unused coffee to throw away. My invention also contemplates such other objects, advantages and capabilities as will later more fully appear and at which are inherently possessedby my invention.

While I have shown in the accompanying drawing a preferred form of my invention, yet I desire it understood that the same is susceptible oi modification and change without departing so from the spirit of my invention.

Referring to the drawing, Fig. 1 is a vertical sectional view of a combination coffee maker and hot coffee retainer embodying the features of my invention; Fig. 2 is a detailed sectional view as drawn on line 2-2 of Fig. 1 on a reduced scale; Fig. 3 is a detailed sectional view drawn on line 2-3 of Fig. 1 on a reduced scale; Fig. 4 is a top plan view drawn on a reduced scale.

The embodiment selected to illustrate my in- 40' vention-comprises an upper coifee making portion In in combination with a lower coffee receiving and retaining portion II.

The coffee making portion III has an open top H adapted to be closed by removable cover I3,

415 and a hollow interior ll. Within the lower portion of said interior a basket I5 is removably positioned with its flange IE- on indentation IT. A top member [8 is hinged to the upper surface of flange I6. Said top member has widely scatto tered spaced pin point openings I8. The bottom 20 of basket l5 has a plurality of closely spaced holes 2|. Extending below the lower portion of my coffee makerin lean integral downwardly extending funnel 22. The funnel 22 has a ring 23 of softer material at its upper outer portion It has been found that constant low to'contact the opening 24 of the lower coffee 'receiving portion II when the funnel 22 is placed therein in normal operating position.

My coifee making portion has inner glass walls 25 and outer glass walls 26 separated by an air space 21. A shell or covering 28 of metal, plastic or any suitable material covers outer glass walls 26. This construction extends downwardly to funnel 22. A handle 29 is attached to shell 28.

The coffee receiving and retaining portion II has a hollow interior 30 of substantially the same size as the hollow interior M of coifee making portion 10. Hollow interior 30 extends upwardly and inwardly to a narrowed opening 24 of sumcient size to snugly receive ring 23 of funnel 22 which extends down into hollow interior 30. Around the neck 3i which surrounds opening is a band 32 which extends outwardly for attachment to a handle 33. A cap 34 is hinged to the handle 33 and is so positioned that when funnel 22 is removed from coifee receiver Ii the cap 34 may be swung to close opening 24.

The coffee receiving and retaining portion H has inner glass walls 35 and outer glass walls 35 separated by an air space 31. A shell or outer.

covering 28 of metal, plastic or any suitable material covers outer glass walls 35.

In usecofie'e making portion In is positioned so that funnel 22 is within the interior 30 of coffee receiving and retaining portion ll. Ground coifee is placed in basket I5 and member II is positioned over basket l5. With the basket I5 and member 18 in position within the hollow interior ll, boiling water is poured into the water 2| in the bottom of the basket l5 into funnel and by meansof funnel 22 into coffee receiving portion II.

The insulated cofiee maker II] has retained the boiling water at a high temperature during the .making of the coffee. The insulated coifee receiver I I now becomes a hot coifee retainer. Coffee maker Ill may be lifted out of coffee retainer II by use of handle 29. Cap 34 is swung over opening 24 and coffee retainer His sealed. Hot coffee may be served for hours by merely swinging cap 34 to open position and with the use of handle 33 pouring the hot coifee out of lip 39 on the outer edge of opening 2d.

Having thus described my invention, I claim: A device of the class described comprising an upper member for making hot coffee having insulated walls forming a hollow interior, said wallsv having an integral inwardly extending portion located substantially above the bottom of the upper member,- a coffee making basket having a flange supported on said inwardly extending portion, said basket so removahly supported being positioned above the bottom 01' the upper member and otherwise spaced from its side walls, aaid upper portion having a funnel continuing from the bottom of its hollow interior, a lower hot cofiee retaining member having a narrow open the lower member, a handle attached to said low 10 er member, and a closure for the open top of said lower memben WILLIAM J.
